UNITED STATES GERTRUDE DAVIS, OF DORAN, VIRGINIA.

ENVELOP.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed August 18, 1908. Serial No. 449,079.

To all whom it may concern:

Be it known that I, GERTRUDE DAvis, a citizen of the United States,residing at Doran, in the county of Tazewell and State of Virginia, haveinvented new and useful Improvements in Envelope, of which the followingis a specification.

This invention relates to the class of paper receptacles, and moreparticularly to envelops, and has for an object to provide means foreffectively preventing tampering with the contents of the envelop duringits transportation and to provide means whereby any portion of theenvelop cannot be broken without detection.

Other objects and advantages will be apparent as the nature of theinvention is better disclosed, and it will be understood that changeswithin the scope of the claim may be made without departing from thespirit of the invention.

In the drawing, forming a portion of this specification and in whichlike characters of reference indicate similar parts in the severalviews,Figure 1 is a rear view of the envelo p showing the same open,Fig. 2 is a rear view showing the envelop closed, Fig. 3 is a plan viewof the blank from which the envelop is formed.

Referring now more particularly to the drawing, there is shown anenvelop 1 comprising a front wall 2 having end flaps 3 and 4, a bottomflap 5 and a top fiap 6. The flap 4 is provided with a cutaway portion7, and at each side of this cutaway portion this flap is provided withadhesive material 8. The Iiap 5 is provided with a cutaway portion 9,and at each side of this portion this flap is provided with a Wing 10having a curved edge 11, as shown. The flap 5 is also provided with asubstantially V-shaped tongue 12 located between the wings 10. Theentire rear surface of the flap 5 is provided with an adhesive 13. Theflap 6 is provided with wings 14, and intermediate of the wings the flapis provided with a substantially rectangular tongue 15. The wings 14 andthe tongue 15 are provided upon their rear surfaces with adhesivematerial as shown at 16.

In practice, the flap 3 is folded on the dotted line A to lie upon thefront wall 2 of the envelop, the flap 4 is folded on the line B to lieupon the flap 3, it being understood 1 that the adhesive material ateach side of the cutaway portion having been previously moistened willadhere to portions of the flap 3. The flap 5 is folded on the line C andall of the adhesive material excepting that on the tongue 12 ismoistened to engage portions of the flaps 3 and 4 respectively. Afterthe contents of the envelop have been properly placed, the adhesivematerial 16 upon the flap 6 is moistened, and the said flap is folded onthe line D in order to insert the tongue 15 between the flaps 3 and 4whereby the adhesive material upon the tongue 15 will efiectively engageportions of the flap 3. The wings 14 of the flap 6 will effectivelyengage the outer surface of the wings 10 and portions of the flap 5 uponwhich said wings 10 are formed. The tongue 12 is finally engaged with aportion of the flap 6 as will be readily seen upon reference to Fig. 2of the drawing.

It will be seen that a novel form of envelop is provided which cannot beopened without detection, and the construction is such that the adhesivematerial upon the various flaps of the envelop cannot be reached shouldan attempt be made to open the envelop by steaming the same as has beencommon in the opening of an ordinary envelop.

I claim:

An envelop comprising a front wall having end flaps, one of said endflaps having a cut away portion, adhesive material at each side of saidcutaway portion adapted to be engaged with its opposite end flap, abottom flap having adhesive material upon one side to engage portions ofthe end flaps, a top flap having adhesive material upon one side toengage portions of the bottom flap, a tongue carried by the top flap andprovided with adhesive material upon one side to engage one of the endflaps and adapted to be disposed between said end flaps, and a tonguecarried by the bottom flap and provided with adhesive material upon oneside to engage a portion of the top flap.

In testimony whereof I affix my signature in presence of two witnesses.

GERTRUDE DAVIS.
